Can I do a battery-only project?

At the moment, this is not yet a supported feature. However, if you would like to quote a battery only project in the format then you can create a project that has only the quote by following these steps:

1. Create a quick roof project 
2. Skip through the roof task (no need to change anything) 
3. Open the financial task and fill in the quote
   
4. Generate the proposal 

This proposal will contain only the quote.
